IMPROVED DEFENSIVE ARMOR FOR SHIPS AND OTHER BATTERIES.

Specification forming part of Letters Patent No. 37,695. dated February 17, 1363.

To @ZZ wim, it may concern:

Beit known that I, R. H. JEWETT, of Mount Sterling, in the county ot' Brown and State of Illinois, have invented a new and useful Improvenient in Defensive Armor for Vessels; and I do hereby declare that. the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a face view of part of the side of a vessel having my armor applied and showing one ofthe other plates broken to expose the interior to view. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a horizontal section ofthe armor.

Similar letters of reference indicate corresponding parts in the several gures.

Io enable others to make and apply my invention, l will proceed to describe'its contruction and operation. A

A A, Figs. 1, 2, and 3, are the inner plates, attached closely to the sides of the vessel by suitable bolts, and having their edges fitted together in any suitable and convenient inanner. B B are the other plates, and O O interposed plates or strips of metal set edgewise between A A and B B. The plates or strips C C are ot' a width equal to that of the intended space between the plates A A and B B, and of any convenient length, and are corrugated and t'urrowed, as shown in Fig. 1 and riveted together, as shown at a a in that ligure. The plates B B have each one of their vertical edges turned in square, as shown at bin Fig. l, and the other turned in square and doubled, as shown at e, to form a double lap-joint with the edge b of the next one, and

have their Lipper and lower or horizontal sides both turned in square, as shown at f1 d in Fig. 2, and anges e f formed upon them, the flange e on the lower side being turned inward, and that, j', on the upper side turned outward, and the flange c of cach is made to lap over the iiangefot the one below it. The parts d d are made of a depth to cause the plates or strips O O,'when set edgewise bctween A and B, to be clamped between them by the bolts g g, which attach B B to the vessel, the said bolts passing through the'iianges e and f and through the slide D of the vessel, as shown in Fig. 2, and being secured by nuts inside. By this construction of the plates B B they are made to constitute boxes for the reception of the plates or strips C C, and the bolts are protected from projectiles. The spaces h h between the plates or strips O O are made t0 constitute air-cells, and the metal forming each of the said spaces is made to form a hollow column, presenting its ends in the direction to resist the impact of projectiles.

What I claim as my invention, and desire to secure by Letters Patent, is

Having the filling-plates O made in corrugated form, united at the angles a and placed endwise and clamped between the plates A B, as herein shown and described, so that iudependent air-chambers h will be formed by said plates, while the plates O will resist all e'xterior pressure on their ends, like pillars, thus securing great strength and buoyancy, all as set forth.
